Insert a closet bolt on each side of the closet flange. Slide on the plastic holding ring provided with bolts to hold them up straight during the toilet installation. Line up the bolts evenly from the wall with a tape measure as close to the center of flange as possible.

Screw a closet bolt nut on each bolt by hand and tighten them evenly with an adjustable wrench. Cut off any excess bolt with a small hacksaw. Snap on each bolt cap cover on its base by hand.

Turn on the water supply and set the water level on the pressure assist tank if necessary. Flush the toilet and check for leaks. Install the toilet's seat according to its manufacturer's specifications.
